Boris Johnson has been up and down the country on the Vote Leave battle bus drumming up support

Once don’t knows stripped out, a Remain vote on June 23 is still ahead by a slither, by 51% to 49%.

The poll also reveals how much immigration has soared as an issue.

Almost as many Brits say they are concerned about the number of EU migrants coming into the UK – 47% – as the ones who fear what will happen to the economy under a Brexit, 49%.

More voters also now believe Vote Leave’s key claim that Turkey will join the EU in the next 10 years – 58% – than pro-EU George Osborne’s warning that we’ll see a recession under Brexit, stated by 49%.

We also asked voters how much economic pain they were prepared to suffer to break free of Brussels control.

In a contradictory finding, three in five Brits – 61% – say that they would be willing to accept a short term economic slowdown in order to see EU immigration controls tightened, which Brexit would allow.

But a significant majority of more than two thirds – 68% – at the same time insist they are not willing to lose any cash at all personally to reduce the number of migrants coming in from Europe.

Only 6% say they would only be happy to lose up to £1-£50 a year to see limits, 5% put the figure at £50-100, 3% at £100-250, 4% at £250-500, and 5% at £500-1000.

But almost one in 10 – 9% of voters – feel so passionately about controlling immigration that they would be happy to lost £1000 a year or more.

The ComRes survey was also carried out over the telephone instead of the internet, which has traditionally produced more favourable results for an In vote.

Despite the late hour, it also revealed 9% of all Brits also still say they don’t know how they’ll vote a week on Thursday.
